Prusa CORE One L+

# Prusa CORE One L+

Overview

Prusa CORE One L+ is a large-format enclosed CoreXY 3D printer for engineering, tooling, prototyping, education, and production work. It provides a 300 × 300 × 330 mm build volume—about 30 liters—with a 60°C actively heated convection chamber, a large all-aluminum AC heatbed, and Prusa's Nextruder direct-drive extrusion system.

The L+ is the August 2026 refresh of the CORE One L. Its main hardware changes are GT1.5 motion belts and an integrated nozzle wiper. The belts are intended to make repeating surface artifacts finer and less visible, while the wiper removes loose filament from the nozzle before printing.

The standard all-metal hotend reaches 290°C and ships with a 0.4 mm Prusa Brass High-Flow CHT nozzle plus a separate 0.4 mm abrasion-resistant nozzle for filled materials. An optional HT Hotend Upgrade raises the nozzle limit to 400°C for selected high-performance polymers including PEKK-CF, PPS-CF, PPSU, and PPA-CF.

For current pricing, configuration, and availability, see the official Prusa CORE One L+ product page.

Technical Specifications

What Changed With the L+ Refresh

The CORE One L+ retains the CORE One L's main build-volume, heatbed, chamber, and extrusion architecture while adding two practical hardware updates.

GT1.5 Belts

The refreshed motion system uses GT1.5 belts. Prusa says the finer belt pitch helps make repeating motion artifacts smaller and less noticeable, particularly on broad smooth surfaces.

Integrated Nozzle Wiper

The new nozzle wiper cleans the nozzle before a print starts. Removing loose filament and small blobs before probing and printing can improve first-layer consistency and reduce contamination on the build surface.

Large-Format Build Volume

The 300 × 300 × 330 mm workspace gives the CORE One L+ approximately 30 liters of printable volume.

That is useful for:

• Large electronics housings
• Machine guards
• Jigs and fixtures
• Automotive prototypes
• Tooling
• Production aids
• Larger educational models
• Multiple smaller parts arranged as a batch

Compared with the smaller Prusa CORE One+, the L+ is the better fit when larger single-piece parts or denser production batches are central to the workflow.

All-Aluminum Dual-Loop Heatbed

Prusa uses a large all-aluminum AC heatbed with dual-loop heating. The manufacturer states that the design keeps temperature variation below approximately 2°C across 99% of the surface under its stated conditions.

The printer automatically detects whether it is connected to a 110 V or 230 V mains environment and configures the heatbed accordingly.

A maximum bed temperature of 120°C gives useful headroom for common engineering thermoplastics such as ABS, ASA, PC, and PA when used with the correct sheet, material profile, and chamber settings.

60°C Active Convection Chamber

The CORE One L+ uses active convection rather than relying only on passive heat from the bed. Fans beneath the heatbed circulate air across the heated surface and raise the chamber temperature to 60°C.

This is particularly useful for larger parts made from materials that shrink during cooling, including ABS, ASA, PC, PA / Nylon, HIPS, and CPE.

For an indexed material example, Prusament ASA benefits from an enclosed, temperature-stable environment when printing larger parts.

The chamber also uses automatic vent control. Low-temperature materials such as PLA and PETG can be printed with the enclosure closed while the printer manages ventilation, whereas higher-temperature profiles can keep the chamber more thermally isolated.

Nextruder and Nozzle System

The CORE One L+ uses Prusa's Nextruder direct-drive extruder with a 10:1 planetary gear system.

The printer ships with two 0.4 mm nozzles:

1. Prusa Brass High-Flow CHT 0.4 mm — installed for high-flow general printing.
2. Abrasion-resistant 0.4 mm nozzle — included for reinforced and filled materials.

The included wear-resistant nozzle is important for carbon- and glass-fiber-filled filaments.

For example, Prusament PC Blend Carbon Fiber and Prusament PA11 Carbon Fiber both require abrasion-resistant nozzle hardware.

Standard 290°C Hotend

The stock all-metal hotend reaches 290°C.

Prusa's current supported-material list includes:

• PLA
• PETG
• Flex
• PVA
• PC
• PP
• CPE
• PVB

With the appropriate filtration workflow, Prusa also lists:

• ABS
• ASA
• HIPS
• PA

The top-level material list therefore stays focused on materials supported by the standard machine rather than mixing in polymers that require the optional HT Hotend.

Optional 400°C HT Hotend

The optional Prusa HT Hotend Upgrade raises the nozzle ceiling to 400°C.

Prusa specifically lists high-performance materials including:

• PEKK-CF
• PPS-CF
• PPSU
• PPA
• PPA-CF
• PP-CF

The CORE One L+'s 60°C chamber makes it better suited to larger high-temperature parts than a smaller passively heated platform.

A 400°C nozzle does not mean every high-temperature polymer will print successfully without further process control. Material drying, chamber temperature, build surface, nozzle material, adhesion strategy, and part geometry still matter.

Automatic Calibration and Motion Control

The printer is factory-calibrated and uses several systems to reduce manual setup.

• Load-cell first-layer calibration
• Mesh bed leveling
• Input Shaper
• Phase Stepping
• Integrated accelerometer
• Dual filament sensors
• Chamber-door sensor

The goal is a workflow that can move from file preparation to printing with less manual intervention than older bed-leveling and Z-offset systems.

Camera and Monitoring

A 1080p camera with night vision is included with the CORE One L+.

It can be installed for remote monitoring and timelapse capture through Prusa's connected workflow, or left out for environments where no camera is desired.

This is useful in production areas, shared workshops, educational labs, and long-duration engineering jobs.

Connectivity, Security, and Offline Operation

The CORE One L+ supports:

• Ethernet
• Wi-Fi
• NFC receiver
• USB-drive printing
• Local-network workflows
• Prusa Connect
• Prusa App
• EasyPrint

Internet access is not required to operate the printer, and the Wi-Fi module can be physically removed for stricter offline environments.

Prusa also offers a separate Critical Infrastructure Edition for organizations requiring additional hardware-level restrictions.

Software

The primary slicing application is PrusaSlicer.

Prusa also provides:

• Prusa Connect for remote printer and fleet management
• EasyPrint for browser/mobile-oriented preparation
• Prusa App for mobile monitoring and control
• Printables integration

The system is not restricted to proprietary filament. Standard 1.75 mm third-party materials can be used with suitable profiles.

CORE One L+ vs CORE One+

The Prusa CORE One+ is the smaller machine in the same family.

The CORE One L+ is the stronger fit when the buyer needs:

• More build volume
• Active 60°C convection heating
• Large engineering parts
• Larger CF-filled or nylon components
• Higher batch capacity
• Better optimization for the optional 400°C hotend

The CORE One+ remains easier to place in a smaller workspace when most parts fit its smaller build envelope.

Comparison With Other Large Engineering Printers

The CORE One L+ competes with other enclosed engineering-focused desktop systems rather than entry-level open-frame printers.

The Creality K2 Plus offers a larger build envelope and active chamber heating, while the Bambu Lab H2D adds a dual-nozzle workflow and broader automation.

The CORE One L+ differentiates itself through:

• 60°C active convection chamber
• Open filament choice
• Offline-capable architecture
• Repairable mechanical design
• Standard high-flow and abrasion-resistant nozzles
• Optional 400°C high-temperature upgrade
• PrusaSlicer and Prusa Connect ecosystem

Price and Availability

The current Prusa US listing shows the CORE One L+ at US$1,850. Based on current exchange rates, the estimated equivalent prices are approximately €1,600 in the Eurozone, £1,368 in the UK, C$2,568 in Canada, A$2,621 in Australia, AED 6,798 in the UAE, and ₹176,672 in India.

These are estimated currency conversions only, not confirmed regional retail prices. Actual prices may differ because of VAT, duties, local taxes, shipping, exchange-rate changes, and distributor pricing.

Power Consumption

Prusa publishes:

• Standby: 16 W
• Preheating: approximately 630 W
• Average PLA printing: approximately 90 W
• Average ASA printing: approximately 215 W

These figures are more useful than a single generic wattage because chamber heating, bed heating, and print temperature change consumption during a job.

Limitations and Practical Considerations

• Physical removable-sheet dimensions are not separately published from the 300 × 300 mm printable area.
• Prusa publishes 500 mm/s travel speed, not a universal maximum print speed.
• The standard hotend is limited to 290°C; 400°C printing requires the optional HT Hotend.
• High-temperature polymers require correct drying, chamber conditions, build surface, and material-specific profiles.
• ABS, ASA, HIPS, and PA are listed with Prusa's Advanced Filtration workflow.
• Carbon- and glass-fiber-filled materials require the included abrasion-resistant nozzle or equivalent wear-resistant hardware.
• Large engineering prints can still warp if material or thermal conditions are poorly controlled.
• The 1080p camera is included but installation is optional.
• Regional pricing can vary.
